A story in the WSJ today about the more than $100 billion of decommissioning work ahead to shut down many of Europe's aging nuclear plants. Each plant requires an average of around $1.5 billion, and often the plant designs do not offer any roadmap for disassembly.
Likewise, Japan has decades of work ahead. Can Japan get this done "on time and under budget", or will it drag out and increase in cost like most things nuclear energy-related? A crucial question.
